Being that I keep them around for emergencies.. I have developed a taste for them.. Some of the newer ones are REALLY Decent.
I have yet to have any "issues" with them.. lol but I don't eat them day in day out.. just when they need to be rotated which I do every once and a while.. especially the ones I keep in the vehicle for emergencies.
Some real life experience with them. Don't be shy about keeping a few extra in your cars folks.. you get stuck somewhere at LEAST you have some food. Don't worry about heat either. Out here in Nevada my in car temps probably reach well over 140, I rotate mine out yearly and have NEVER had one go bad on me.. even in that kind of heat. They keep pretty well in super hot conditions as long as you rotate them out every year or so.
If that is all you are looking for, I will have my grandmother send YOU the Christmas poundcake this year.
Where do you buy them?
